The Minecraft API is going to make mod development SO much easier. No more decompiling and patching hacks. I've been waiting for this since Mojang snagged the Bukkit team. I look forward to the first client/server builds that support it.

I added a Jenkins build job for it on BuildHive so anyone can download the bits if you want to play with the very limited banning API that they apparently have so far :) https://buildhive.cloudbees.com/job/swashbuck1r/job/Minecraf...

I hope they'll consider adding a build job for the official project.
